This weekend's hottest tip concerns that home away from home for Burners, Tribe.net. The social site has long been the Friendster of Valley hippies and geeks whose social calendar revolves around the Burning Man summer festival. (Until recently, that included Google founders Sergey Brin and Larry Page.)

This is the scoop: Tribe's struggled long enough for a breakthrough. The investors don't see any buyout coming to recoup their cash, and according to a tipster, they might give up on the whole operation very soon.

But the tipster says that Tribe's owners might woo back co-founder and former CEO Mark Pincus (pictured). Will he remarry this bride now that she's old and gray?
